Abstract (en)
The field effect transistor has a gas-sensitive layer containing titanium.
Abstract (de)
Der Gassensor arbeitet nach dem Prinzip der Messung der Austrittsarbeit zur Bestimmung von Ammoniak und/oder Ammoniak-Derivaten und weist eine gassensitive Schicht (1) auf, die Titan entweder rein oder in einer Verbindung enthält. Anwendung beispielsweise an Kühlanlagen und zur Tiermast. <IMAGE>
